Dynamic simulation of whole driving axle is chosen to make up the shortcoming that only surface vibration data of driving axle can be obtained by the tests
thus the stress
displacement and acceleration at any position are revealed. A 3D model and a finite element model of driving axle is established and verified by comparing the results from modal tests and computing. The dynamic simulation for whole driving axle is conducted and verified by bench test. It demonstrates that the surface vibration data of dynamic simulation of whole driving axle coincide with that of the bench test
and the obtained driving axle interior data by dynamic simulation can directly support vibration and noise investigation of driving axle.
